This means that no matter what the engine speed it, it is always performing at its peak efficiency. One of the advantages of a CVT is its ability to continuously change its gear ratio. Which Is Better Between CVT and Automatic Transmission? Toyota says that using these new fixed gear ratios will not only feel more like a regular transmission it will also increase belt efficiency and improve performance. As the vehicle speeds up, the transmission will switch this out, so it starts working as a CVT. The launch gear is almost like the first gear in a regular automatic transmission. CNET says it now uses what they call a Launch gear to provide drivers with the feeling of a conventional transmission. Toyota recently made some changes to its CVT. The hydrostatic CVT uses pumps to control fluid flow, which then produces a rotational motion. The most common type is the pulley-based, but some other types include the Toroidal CVT, which uses rotating discs along with power rollers to produce the same result as the pulleys. Since neither the pulleys or the belt are fixed, they can provide an infinite number of gear ratios, unlike the automatic, which has a set number of gears. When one pulley gets larger, the other one gets smaller. The width of the pulleys changes depending on how much power the vehicle needs. One pulley connects to the engine, and the other connects to the wheels. An automatic also has a set number of gears, but it uses a hydraulic system that responds to pressure created by the conditions to determine the gear needed without any input from the driver.Ī CVT is similar to an automatic in that it doesn't use any input from the driver, but that is where the similarities end. A manual has a set number of gears, and the driver determines what gear ratio they need. In order to see how a CVT works, How Stuff Works explains, you need to understand a manual and a traditional automatic. This is part of the reason that they are becoming a more popular choice for automakers in many vehicles. Advantages of CVTĭepending on the vehicle and the driver, a CVT can provide a smoother driving experience when comparing it to a traditional automatic.Īccording to Carfax, one of the most significant advantages to having a CVT is that they are often more fuel-efficient than a regular automatic. What Does CVT Stand For?Īutotrader explains the term CVT stands for continuously variable transmission. It is sometimes referred to as the shiftless transmission and is a type of automatic. The CVT is the newest type of transmission. Even if you don't know much about how a transmission works, you have probably heard of the manual and the automatic.
